The county Medical Examiner's office will determine the cause of death.

Authorities say Fitzmaurice and a friend were on an elk hunt south of the Grand Canyon and Tusayan.

The ATV Fitzmaurice was driving rolled over and landed on him. His friend was unable to lift the vehicle off Fitzmaurice and called 911.

Investigators say it appears Fitzmaurice was driving too fast heading into a series of turns in the road and the ATV rolled after a front tire struck the dirt berm of a water drainage alongside the roadway.

There are countless places to go for a great view of the Grand Canyon. Akin's Perch is one of them. That's where the artist Louis Akin - in the early 1900's - painted one of his large-scale works of a storm swallowing up the Canyon. In this month's Canyon Commentary, Scott Thybony visits Akin's Perch to see the monsoon through a painter's eye.
